So I said I would update how this gig went. Overall this gig went super smooth! We had ample time to set up. I had ample time to do what I needed to to and connect everything properly. I was able to be out in the crowd area instead of right by the PA. Most importantly, we had the time to do a proper sound check! I took some advice form this thread and sound checked a vocal channel and duplicated the settings on all the channels. Awesome by the way! Thank you. I brought the tools suggested in this thread, extra DI's, cables etc. Needed all my DI's and all my extra cables to make things work. We had a few cable problems but nothing that wasn't fixed in a short period of time. The sound check for the most part was organized and I had a talk back mic working so it went rather quickly. The band had a monitor mix that they were really happy with. I almost fell of my chair when one guy told me he needed to be turned down. He is usually the me, me, me guy.
After about a 15min sound check we started and after a song or two everything was dialed in and I really didn't have to do much. There we some effects processors looking rather pretty that evening if you know what I mean. Overall I am much happier than last weekend. I had everything as simple as possible and got the groups right. I could then monitor the main output in my headphones. The band could hear themselves and there were multiple people saying they liked the sound. I wasn't pushing it to ear piercing levels. Just enough so if your in the dance area you can feel it. 10' back was about 95db. Yes, I do carry a db meter. At the bar people could talk. The managers at this place were really happy with that.
The best part. I finally got paid! So I am chalking the first experience up as a learning experience. That experience taught me to simply be more prepared. This week it paid off.
Thank you everyone for your advice. I really do appreciate it. I can't wait to do the next gig!
